Hi Joe,

For the record, most computers only need one of the two USB plugs attached - some older systems that can't supply the necessary amount of power through one port will need two.

If it's still not working after following that guide, please drop us a line at sales@pgmusic.com, or call us at 1-800-268-6272 and we'll get the replacement procedure going as soon as possible for you.

Best regards,
Will
